attached big documents could not opened in FK03

Hello Gurus,

we have a strait issue in our system.

In transaction fk03 after we choose a vendor, we try to open a document from attachment list.

If this document is simple small it will opened.

But if the document is bigger, in our case more than 10MB, we get an error.

The file could not found at the local filesystem of the client.

We checked it, and find out, that the file is created at /usr/sap/SID/DVEBMGS$$/work with the full path of the client.

But the client directory is empty.

/usr/sap/SID/DVEBMGS44/work/D:\Users\testuser\Documents\SAP\SAP GUI\test_testuser_20130612133919.339_X_20130703060751.971_X.pdf

Has someone a suggestion what went wrong?!

We have no ideas anymore.

kind regards

Chris
